Juno-106 SysEx in detail

In general, the Juno-106 does not use the Midi Command "Control Change" (Bn hex).
Instead, it uses System Exclusive (SysEx) messages.
The only Control-Change messages which were used (and documented in the Owner's Manual) are:

Control Change: Modulation

code(hex)

Bn

Control Change

n = Midi channel (0-F)

01

vv

value

00 = Modulation off7F = Modulation on

Example:

Set Modulation off

Control Change: Pedal

00 = Pedal hold off7F = Pedal hold on

Example:
B0 40 7F
Set Pedal hold on

When controllers (faders, switches) are changed, a SysEx message will be sent.
Some of the switches were grouped together and the data are bit-masked.

Note: if you have a PC sequencer where you can enter SysEx data, it's likely that you don't have to enter the leading "F0" and the trailing "F7" - they mark the beginning and the end of the data and your program may wrap the data into these bytes.
